As with so many engineers of the day, Purdy’s skills were about to come into ever-greater demand, strongest coming from McDonnell-Douglas Aerospace, who lured him further west, to St. Louis, in September of ’55. At the time, few knew where the job would take him, but “over the next thirty-nine-plus years, I worked on one Mach 2 jet fighter program, three missile programs and eight space programs, including five manned space programs,” recalled Purdy in February.
“I joined the Mercury team in early 1959, working in the electrical power and sequential systems design group, and stayed with the Mercury program until completion,” said Purdy. After a quick switch to Project: Gemini, Purdy was a key member of the electrical design team that monitored the electrical wiring system and fuel-cell development. Soon, he would know every detail of Gus’ “Molly Brown” and those that followed, for he was assigned to the Gemini Operations Team responsible for the electrical test complex design and the spacecraft’s electrical systems testing.
After Gemini, Purdy joined the Manned Orbiting Laboratory program to lead the electrical design of the heat-shield qualification vehicle.
In his spare time, Purdy gave his full attention and expertise to program management of the last two orbital attitude maneuvering system pods for the space-shuttle program, the modular power subsystem for NASA’s multi-mission modular spacecraft, electrophoresis operations in space and the transporter electrical storage system and external lighting modules for the international space station.
